CVE-2026-46282

Kernel crash via unchecked device property read

Published Jun 8, 2026 · Updated Jun 8, 2026

NULL pointer dereference in the Linux Kernel admv1013 driver allows local users to crash the kernel during device probing. The probe path ignores a failed device_property_read_string() call and passes the uninitialized str pointer to strcmp(), which dereferences an invalid address. Reachability requires CAP_SYS_MODULE or root access to bind the driver and a malformed device tree that the attacker cannot influence.
